The sine of any acute angle is equal to the cosine of its complement. The cosine of any acute angle is equal to the sine of its complement. of any acute angle equals its cofunction of the angle's complement.
A
C
B
Since m∠A = 22º is given, we know m∠B = 68º since there are 180º in the triangle. Since the measures of these acute angles of a right triangle add to 90º, we know these acute angles are complementary. ∠A is the complement of ∠B, and ∠B is the complement of ∠A.
If we write, m∠B = 90º - m∠A (or m∠A = 90º - m∠B ), and we substitute into the original observation, we have:
Answer:

Answer:
Option(B) is the correct answer to the given question.
Step by Step Explanation
We know that
Here A=amount
r=15.98%=0.1598
n=365
t=1
Putting these values into the equation
Now we find the interest
I=
Therefore effective interest rate of the last year can be determined by
=0.1720 *100
=17.20%
